Subjects whose wounds heal prior to Visit 12 are expected to have a follow-up appointment 12-14 weeks after their wound has healed. Subjects whose wounds do not heal by Visit 12 are expected to complete a follow-up appointment 12-14 weeks after their last appointment. The objectives of this are to determine the frequency of complete healing between the two treatment groups and to determine the number of wounds that had healed by the end of the treatment phase and remained healed for each group at the follow-up appointment.
